Fig. 2 is a-plan of the apparatus.Fig. 3 shows one constructional form of ball carrying and 4spring clutchin part section. This clutch is employed for giving I rotation to theball about an axis in any direction. Fig. 4 shows another construe# ltional form of clutch in plan. This clutch is forgiving a spin totheball about allorizontal axis at right angles to the line .of

flight. Fig. lshowsin elevation and part section a simpler form Aofclutch for delivering the ball spinning about an axiscoincie dent' orapproximately so with the direction l .of flight. Fig. 6 is-an end Viewof same,

and Fig. lis a plan of same. Figs. 8 and 9 are Views of the universaljoint employed to carry' the clutches shown in Figs. 3 and 4.

Like letters of reference refer to like parts in all the figures.

Referring to Figs. 1 and `2, A is the base" lor 'support of theapparatus.

' is hinged at G to the base A. This enables the throwing arm D and aportion of the frame to be raised at the front end inorder to alter thetrajectory of the ball thrown. The frame is supported when raised uionthe cross bars of the hinged rack H.' he height ofthe frame may beadjusted by placing it in another hole of the adjustable or supportraclt H.,

' The throwing arm D is pivoted on the in -I inounted on the b'ar F., Itis connecte to the front bar J of4 the frame by the sprlngl K. It isalso connected to the back bar L of the frame by the cordM. The cordl\lis secured at theother end tio the-buffer' 0 O, are guide bars, oneou each lside of.

the throwing'arm D, to revent any undue lateral movement of the t rowingarm.

`ting the clutch gie with the carrier D1, and at the same time F1 F1,are bars to more firmly secure the end members J, L, of the frame tothe' lower bar F. The clutch carrier D1, which may' be a flat or roundrodof any suitable matelrial is secured to the top of the throwing armD, b f means of set screws, and its position A1s a Justable 'lhe clutchP 1s secured to the carrier D1 by means ofthe adjustable' joint D2,which permits of adjusting. or set at a dierent vertical an- .The clutchsired mark, which mark-ma .side that of receivin a ringl ball bearingthe -wire 'connection PI. The wirePlfis4 allows-said clutch to be swunglaterally.

F ig.. 3.

The string, wire or cord D5 is employed to release the clutch l. ashereafter described. The cord D5 is connected at its lower end to theback frame member F1, it passes behind the eye D3 and thence through thecenter of the hollow rod Illl to release the clutch. The lcord D'5becomes taut when the throwing arm D Vis near the end of its stroke, andso exerting a pull on the clutch mechanism releases the ball.

The dotted lines Fig. lA indicate the-other position of the4 throwingarm D. lVhen drawn back to this position extendin the spring K, thecatch or hook D4, is p aced behind the pin or eye D3, to hold it in thisposition. The clutch P is then adjusted to the desired position vforthrowing. The

clutch P which is mounted on ball bearings on-the rod P1 is thenArotated in whichever direction it may be desired to spin the ball. Thisis preferablydone by means of'a small pulley fixed to the spindle suchas shown P2, Figs. 3, 5, 6 and 7 A piece 'of Stringer the like is woundaround the pulley and being pulled in `uuwinding rotates the clutch andball at a good speed. The catch ,or hook D4 is then released by hand.The spring K pulls the throwing arm D sharply forward, and when near theend of its stroke, the clutch P releases the ball Q, which is thusthrown spinning at the wicket or debe a spot on either side of or infront ot the wicket or the like.

Referring toFig. 3, the ball Q is held by the four levers of which P3,P21 only appear in 4this view. The said four levers are. mountednfulerum pins .on -the disk or end flange of the sleeve P7, which sleeveis adapted to rotate freely Aon ball bearings fon the solid continuationof the rod or spindle F1.. Each lever is 4provided Iwith a spring asshown on the lever P3, which tends to open outwardly the lever andrelease the ball, that is to say to place the levers radially to the rodP1. The pulley P2 in this figure serves another and additional .purposebethe string used for Spinnin the ball. T e pulley P2 is mounted to side longitudinally on the'sleeve P. The flange of the ulley'P2 ispressedforward assisted by tlhe action of the sprin P and is so placed that theshorter arms o 'the -levers I, P4, Pi'andP (the latter'not' shown) rest'upon its edge. The longer-armsof the levers' are thus pressed against'the ball Q to hold it., In order that the, pulley II may lie-slidbackwardly soy as to release the levers and ball, and yet be permittedto rotate freely, the' ulley is provided'with 9 having fitted thereto Pis shown to a larger scale in passed through a Slet 24diet inde iii thehollow rod l, and the String` or Cord l)i is secured to the wire insidethe hollow rod. When the string is pulled, the tour levers are releasedand tty open ley the action ot their Springs eo releasing the ball.

Referring to Fig. el, the ball Q is held between two shallow cups R R1.These cupe are rigidly fixed to spindles which Carry the pulleys PT l attheir other ends. 'l` he said Spindles are mounted on ball bearingsfitted within the tubes "l2 R3, te allow of 'free rotation of the cupsand ball. rl`lie tubes are carried by brackets as shown fixed to thesliding sleeves lll The Said sliding sleeves llt R aleo carry the pinsRb' RJ respectively, These pass through slots in th inner fixed tubes,l5 R9 respectively. The length oit the slots Shown dette i, determinethe degree ot movement permitted to the sleevesl iipon the said innertil'ied tubes RT llt. Within eaeh of the Said inner tubes RT lli islitted a spring, one end et which ie Secured in the tube end, and theother to the Said pine. Consequently the Said pins, and theret'oi'e thesleeves and (rups Connected thereto the Said ai'e always pulledoutwardly by springs. ln order te hold the cups preseed against the hallin opposition to the tension et the said Springs. the doiihle lioolr ordeteiit lt provided.
